Abstract

PURPOSE:To improve the adhesion of a head and a recording medium by fixing a head mounting angle to a fixing spring, energizing the head on the side of the recording medium by simply abutting and energizing another presser spring, and controlling the rotation of the head by abutting a safety board fixed to the head mounting angle near the fixed edge of the presser spring. CONSTITUTION:A fixed spring 10a fixed to a head mounting angle 9 and energizing a magnetic head 8 on the side of a recording medium 7, a presser spring 106 abutted to at least one of this fixed spring 10a, the head mounting angle 9, and the head 8 and energizing the head 8 on the side of the recording medium 7, and a safety board 11 fixed to the head mounting angle 9 as well as abutting this presser spring 106 to a fixed edge part E, are provided in construction. Namely, the head 8 inclines to a weak side in the movement direction of the recording medium 7 and in the direction of the right angle and followed by the inclination of the recording medium 7, while the head 8 is hard to incline in the movement direction of the recording medium 7 so that a stable posture can be kept. Thus, the adhesion of the head 8 and the recording medium 7 can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a head support device such as a magnetic card read/write device for performing magnetic recording and reproduction on, for example, a magnetic card.

Conventional technology In recent years, magnetic cards have come to be used not only as ID cards for automatic bank payments and credit confirmations, but also as a means of payment for usage fees for various automatic service devices, including public telephones, with particular emphasis on the latter use. tends to expand rapidly.

In addition, magnetic card read/write devices that are compatible with the use of these cards have traditionally been used in large-scale equipment used indoors, but with applications across a wide range of fields, they have been adapted to handle harsh usage conditions such as outdoor use, and have been used in various service equipment. There is a need for a compact device that can be easily integrated into the system. In this magnetic card read/write device, the magnetic head, which is the core of the magnetic card read/write device, follows the tilt of the card due to card deformation (warp), etc., and ensures that the magnetic head is in reliable contact with the card surface. A magnetic head support device is required.

Conventionally, this type of magnetic head support device has had a configuration as shown in FIG. In FIG. 3, reference numeral 1 denotes a magnetic head, which is fixed to a head mounting angle 2. The head mounting angle 2 to which the magnetic helad 1 is fixed is attached to the fixing spring 3a of the head mounting spring 3. At this time, the magnetic head 1 is urged toward the magnetic card 4 via the head mounting angle 2 by the spring 3b holding the predetermined fulcrum B. The head mounting spring 3 is attached to the main body 5 of the magnetic card read/write device.
mounted on.

The operation of the magnetic head support device configured as described above will be described below.

The magnetic helad 1 is a presser spring 3b of the head mounting spring 3.
As a result, it is biased toward the magnetic card 4 side in FIG. 4 and comes into close contact with the magnetic card 4.

When the magnetic card 4 is fed tilted due to deformation (warp) or the like, a gap A is generated between the magnetic head 1 and the magnetic card 4 as shown in FIG. The fixed springs 3a of 3 are twisted at two leg portions K on both sides, and the magnetic head 1 is tilted to maintain close contact with the magnetic card 4.

Problems to be Solved by the Invention In such a conventional configuration, since the fixed spring 3a of the head mounting spring 3 shown in FIG. It is excellent. However, due to the displacement of the magnetic head 1 and the frictional resistance between the magnetic head 1 and the magnetic card 4, the magnetic head 1 tilts in the downward direction in FIG. Furthermore, since the core gap G of the magnetic helad 1 moves relative to the magnetic card 4, the magnetic recording position with respect to the magnetic card 4 may change, leading to errors in reading and writing magnetically recorded data. There was a problem.

The present invention solves these problems by making the head follow the inclination of a recording medium such as a magnetic card in the head support mechanism, and by suppressing the rotation of the head in the card running direction. The purpose of this is to stabilize the posture of the head, improve the adhesion between the head and the recording medium, reduce the incidence of data reading and writing errors, and increase reliability.

Means for solving the problem and to achieve this object the present invention comprises a head;
a head mounting angle that fixes the head; a fixing spring that fixes the head mounting angle and biases the head toward the recording medium; and abuts against at least one of the fixing spring, the head mounting angle, and the head. The apparatus is configured to include a presser spring that biases the head toward the recording medium, and a stabilizer that abuts the fixed end of the presser spring and is fixed to the head mounting angle.

Effect: With this configuration, the head tilts with a weak force in the direction perpendicular to the direction of movement of the recording medium, and follows the tilt of the recording medium, and the head does not tilt in the direction of movement of the recording medium, maintaining a stable posture. It is possible to maintain a constant relative positional relationship between the head and the recording medium, and at the same time improve the adhesion between the head and the recording medium, reduce the incidence of data reading and writing errors, and improve accuracy. become something that can be done.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a magnetic card read/write device according to an embodiment of the present invention. In FIG. 1, 6 is a flat belt, which allows a magnetic card 7 to be used as a recording medium.
is sent, and it passes through the magnetic head 8. The magnetic spatula 8 is fixed to a head mounting angle 9, and is attached to a fixed spring portion 10a of a head mounting spring 10.

At this time, the magnetic head 8 is biased toward the magnetic card 7 via the head mounting angle 9 by the presser spring 10b having a predetermined fulcrum. A stabilizing plate 11 is integrated into the head mounting angle 9, and the holding spring 10b
The support fulcrum E is in contact with the vicinity of the fixed end. The head mounting angle 9 is fixed to a main body 12 of the magnetic card read/write device.

The operation of the magnetic head support device of the magnetic card read/write device configured as described above will be explained below with reference to FIG. The fixed spring portion 10a of the head mounting spring 10 to which the head mounting angle 9 is fixed has two leg portions M on both sides that are thin, making it easy to rotate in both the N direction and the P direction. 'fl! The pressurizing force on the i-card 7 side is generated by urging the presser spring 10b by abutting it at a support fulcrum. The stabilizing plate 11 is a support fulcrum E
Since it is in contact with the fixed end of the presser spring 10b, P
The rotation in the N direction is not prevented, but the rotation in the N direction is suppressed, and the magnetic helad 8 now moves on an arc centered on the support fulcrum E, so that the contact position R with respect to the magnetic card 7 is in good contact. can get. Note that 8a is a core gap.

Effects of the Invention As described above, in the present invention, the head mounting angle to which the head is fixed is fixed to a fixed spring, and the head is urged toward the recording medium by simply contacting and urging another presser spring. The stabilizing plate fixed to the mounting angle comes into contact with the fixed end of the presser spring to restrict the rotation of the head, so even if the recording medium is fed at an angle, the head will fully follow it and keep the head from tilting. Improves adhesion to the recording medium. In addition, even if the displacement of the head or the frictional resistance between the head and the recording medium changes, the posture of the head and the recording medium will not change, and the close contact between the head and the recording medium will be maintained, resulting in errors in reading and writing recorded data. This has the effect that the reliability of recording and reproduction can be improved.
